Carmen Roberts - Katherine Blake

Dr. Katherine Blake (formerly named Wendy Mulligan) was the psychotic girlfriend of Chris Warner (Michael Galvin). She arrived as the replacement for Meredith Fleming (Stephanie Wilkin) and quickly got on Chris' good side. However when she failed to save the life of Tom Neilson (Adrian Keeling), she made an enemy of Darryl Neilson (Mark Ferguson) and ended up showing her true colours when she overpowered and threatened him when he dove into her private life. Katherine started to date Chris but some started to see her true self when a British patient named Nora recognized her from a news article in England and Katherine attempted to murder her whilst a young patient - Sarah-Jane (Lauren Porteous Morcom) watched. Kirsty (Angela Dotchin) began to research Katherine's past and found herself framed for robbery. She eventually discovered Katherine was really named Wendy, had murdered her husband and was not really a doctor. A desperate Katherine attempted to flee the country but when confronted by Chris, attempted to murder him. Katherine was arrested and upon release from bail, announced to Chris that one day she would become a doctor before leaving.
